A year after Jackson Audio’s release of the 1484 Twin Twelve — an astoundingly spot-on re-creation of the tone and EQ of Silvertone’s legendary mid-’60s half-stack — some well-paid attention to a crucial element of the very same amp’s effects channel emerges: the 1484 Twin Trem pedal. Paying proper homage to the 1484’s original tremolo effect, the 1484 Twin Trem presents that charmingly classic Optical tremolo effect on the left side of the pedal. But wait — Jackson Audio’s upping the ante! Stationed on the right side of the pedal is an additional Harmonic tremolo, affording guitarists a lusher, out-of-phase split-signal tremolo option. Pick your poison, or blend the two for exciting percussive effects (and a colorful bulb display) — even place both effects at separate points within your chain courtesy of per-tremolo I/O! Era accuracy abounds with Speed and Depth (Strength) dials for each effect, not to mention a presentation that perfectly matches the vibe of the original unit, complete with red pointer knobs, a black and brushed steel faceplate, and that iconic crystal lens cap. 

A tale of two trems

True to the original 1484 Twin Twelve amplifier, the 1484 Twin Trem houses the classic Optical tremolo that perfectly complemented the amp’s bell-like tonality. Engage it, and you’ll get a beautiful blue signal, which ticks in real-tremolo-time within the miniature Volume control dial. Use Depth to determine the intensity, and allow the Speed knob to take you from slow and subtle pulses to fast and fluttery effects with one simple turn. Country western wobble? Link Wray raucousness? Get your fill of both and everything in between.

Kick on the 1484 Twin Trem’s right switch to engage the pulsing red glow of the Harmonic tremolo, and you’ve got an entirely different story. By splitting your high and low signals and then blending them out of phase for marvelous modulation, this Harmonic switch is your ticket to a much more luscious tremolo effect. The same Volume, Depth, and Speed controls apply on this side as well, granting you access to all times and intensities.

Go ahead and switch both trems on — now we’re talking! Combining both effects turns the crystal cap into a fitting shade of magenta and makes for some exciting sonic experimenting laden with tonal richness and unique percussive interplay. It’s a breath of fresh air for stereo setups and allows you to place two different tremolos at multiple positions across your board using a single pedal for remarkable amp tremolo and post-reverb signal accuracy.

Vintage vibes on tap

Don’t get us wrong: the sonic power of the 1484 Twin Trem is phenomenal — but just look at that aesthetic! Meticulously designed to render a realistic presentation of the original 1484 amplifier, the 1484 Twin Trem looks straight out of the ’60s and is a surefire contender for the handsomest effect on your board. Brushed steel with black striping, that sleek Silvertone script, the control font, red pointer knobs, the crystal lens cap — it’s all here with stunning precision. For fans of the original amp, players rocking Jackson Audio’s 1484 Twin Twelve stompbox, or guitarists looking for a to-die-for tremolo, the 1484 Twin Trem is the top pick you’ve been waiting for.
